Vray And Dual Opteron Systems

[indigooo]

Anobody have tested vray in a dual opteron box? I´m planning to get a new machine and think that spending money now in a xeon dual is not a good idea (32bits processor, more expensive)

Thanks in advance

Hi indigoo !

I use Vray on dual opteron and works fine here !
We are waiting for the 64bit update of all the softwares...
It will be long before we use all the potentiality of the opteron...
So be sure, you want to get something you wont use at 100%

Bye

well, i just wanna add a point here... the fact that some
people are running dual processor with no problems so far
does not mean that it is certified ok.

as we all know, problems and glitches surface with different
kinds of 3d scenes / lighting / materials.

i now have confirmed for a fact that my hyperthread machine
does give higher chances of splotches. not all the time.
in fact, i thought it was some of the usual problems that caused
my splotching. but upon reading someone's post suspecting HT,
i did a check. confirmed its the HT machine that has this problem.
disabling HT in bios helps the problem to a large extent, but
some scenes in my problematic file still display splotches..which
when rendered in a non HT machine, is perfectly fine.

thot u might wanna know since HT is kinda like dual processors?

[indigooo]

there is a huge differente between a HT p4 and a real dual machine, the ht doesn´t mean you have real double process

my two cents,
like gafl said, it will be a long time until you can use the full power of a 64bit cpu. I would pick up prestonia xeons, dont wait for the noconas (they are too hot / prescott core). Get the asus pc-dl deluxe (canterwood chipset for dual xeons ), put some ddr-ram on it and enjoy the HT under Vray. I bet you'll outperform a opteron with that system.

[indigooo]

but also twice expensive, it is the problem

Sorry Indigooo !!

I cannot test my system, I render a very long animation with...

All I can say is that I have 2 opterons 242 and it is equal to
my 2 MP Athlon 1800+, that's not good at all.I have been abused by
the dealer...

So I regret a bit...But I ' m ready for the 64 bits generation.

I should have bought 2 MP 2800 or equivalent...For the same price,
I would gain a lot of rendering time.

i still dont get this whole HT thing. ive got a dual HT machine here that never crashed, froze or gave blotches.

[Randy]

compared with a opteron setup, the price should be the same.
Yeah Da_elf, HT rocks, its like a turbo for vray

Dual Xeon 2.8's here and a 3.0ghz P4 both with HT on and no issues for a few months now with max 4, 5 and 6 with V-Ray.

just finished rendering more than 60'000 frames during the last three weeks with
6x 2xeon 3.066 under xp pro with ht

without great problems

-10 frames looks strange

-experience just about 5 time strange freasing rendering

for me 2xeon 3.006 was the only solution to finished my work in time
and what i can say it's a great machine very stable
we have 14 athlon 2000-3000 on our renderfarm and we have more problem witht them than with the 2xeon

last but not least
when you see 24 bucket in dr...

niiiiiiiiiiiiiice serge

thanks

Speed benchmark....Xeon

As you guys can see..xeon can do the job very well. but make sure you know what youre buying to achieve the speed. I suggest you guys do the bench if you want to know how you machine is compared to others...check the link indigo has on her post...time varys from 30 min to 18...i got 13. we all spend the same amount of money...do we?
